1
The chemistry of phosphorus pt.1
By Laura Roa
2
Chemical properties Different from Nitrogen: Nitrogen’s pi bonds
Nitrogen’s electronegativity Size of Phosphorus atom D orbitals on Phosphorus
3
Elemental form differences
Several solid forms of phosphorus. White phosphorus Black phosphorus Red phosphorus Forms phosphides
4
Phosphine Na3P + 3 H2O = PH3 + 3 NaOH (formation) Analogous to Ammonia
Small affinity for protons Pyramidal molecular structure: Exception to VSEPR
5
Phosphorus oxides and oxyacids
Phosphorus reacts with oxygen to form oxides: Tetraphosphorus decoxide Affinity Dehydrating Dissolvation Phosphate minerals
